To all 1li/0m it may concern Be it known that I, ANDREW CHRISTIAN- son, a citizen of the United States, and resident of Butler, in the county of Butler and State of Pennsylvania, have invented a new and useful Improvement inHopper-Cars; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to hopper-cars- The object of my invention is to, improve the construction of these hopper-cars in certain ways, so as to obtain a more durable and stronger construction, to enable the car to sustain the increased loads and the necessarily greater wear and tear to which said cars are subjected by reason of such increased loads.

To these ends my invention comprises the novel features hereinafter set forth and claimed.

In the accompanying drawings. Figure l is a side elevation of a portion of a hoppei-car embodying my invention; Fig. Q is a view plan and view section on the line 2 2 Fig. l; Fig. 3 is a vertical section of portion of a hopperrar, Fig. 4 is a section on the line HL Fig. 3; Fig. 5 is a section on the line 5-5, Fig. 3, and Fig. 6 is an enlarged detail.

In the drawing, the numeral 2 designates the side-plates and 3 the inclined end-plates of a suitable hopper-car connected by angles andbraced in the ordinary manner, which it is not deemed necessary to describe in detail.

The center-sills 4 consist of channel-beams with the flanges inwardly turned. The inside hopper-sheets 5 are secured te the center-sills 4, and the upper ends of said hopper-sheets are inclined as at 6, to form the central ridge extending from one inclined end-plate 3 to the other, and riveted thereto.

The outside hopper-sheets 7 are riveted to side-plates 2 of the car, and the inside jointstrips 8 at their lower ends overlap the upper ends or" the hopper-sheets, and are riveted thereto as clearly indicated 1n F It.

The bottom of the car is divided into a4 series of hoppers 9 on each side of the center-sills, which are made up of the inside hopper-sheets 5, the outside hopper-sheets 7 and the inclined hopper-plates 10.V The vertical diaphragm `plates il extend from the outside hopper-sheets to the inside hopper-sheets and to a point above the same, said plates being;r flanged as at 12 and riveted to the side plates Q as indicated in Fig. 2.

Cross-braces 13 made up of angles 14 are secured to the upper ends of the vertical plates l1, and said angles have at their ends the Ganges let which are riveted to the sideplates. The sloping` surfaces of these braces prevent the collection of the ore, coal, or othei` material contained within the car, and said braces act to stiflen and strengthen the sides against inward or outward bulging. Like braces 1G extend from side to side of the car at a point near the top thereof Rivet-ed or otherwise secured to the ineline hopper-plates 10 are the stiilening bars 17, which extend below the center-sills transversely oi the car. These bars'may be of any suitable form, either rolled or pressed, those illustrated being in the form of angle'- bars. Braces 18 are riveted to the flanges 19 ot the anglebars 17 at suitable intervals, said braces acting to strengthen the inclined hopper-plates against the strains of the load. These brace-plates 18 may be formed by pressing and have the strengrtheninp.` ribs 2O formed therein. The hinged lugs 21 are secured to the anfrlebars 17 at suitable in-l tcrvals, and from these hinge lugs the doors tion and the hopper-plates are greatly stiff4 i fened and strengthened.

What I claim is:

1. In a hopper-ear. the combination ofthe ccntersills, the inside hopper-sheets, inclined hopper-plates extending below the center-sills, and stifening members securedJ to said inclined hopper-plates below said center-sills and extending through sind hopy per-sheets.

'2. 1li a hopper-car, the combination of n tostmony whereof, I the. said ANDREW center-s1l1s, mslde hopper-sheets, lnchnod CMRISTIANSON, have hereunto set my hand. hopper-Mates extendmg below the sold cenf n tezslls, stffening angle-bars connected to ANDREW UHRISTANSON' said hopper-p1ntes below said center-sills, Wtnessesz and extending through said hoppelshets, J. KELLER,

and braces Connecting said anglo-bars. JOHN F. `WILL.
